Caption factbox

I'm facing something of which I think it must be very simple.
I just am not seeing it.

I have created several custom factboxes.
When I change the language in NAV the caption changes.. which is good.

But, the standard NAV factboxes stay in Dutch.

As you can see in the print screen, the first checkbox should show: “Customer Statistics - Bill-to Customer”. All the other captions changed (see they yellow marked). And my custom factbox also shows a ENU caption.



I've checked the following settings:
• Caption ML in the sales order list page (9305)
• Caption ML on the factbox

Looking forward to reading the answers and I hope I won’t feel to stupid afterwards
